At a time when we are all being asked to consider the environmental impact of motoring, a German sports car manufacturer has come up with a green car that delivers minimal eco disturbance without sacrificing performance. The specialist company, Ruf Automobile GmbH, has produced an electric concept-car based on the Porsche 911. The eRUF may look like any other Porsche, but beneath the bonnet the 3.6 litre boxer engine has been replaced by a 150kw/204 hp three phase AC motor, powered by 96 lithium-ion phosphate base batteries.
The eRUF cannot quite outdo a conventional 911, but it performs to impressively high standards. It can accelerate from 0 to 100km/h in less than seven seconds, and has a maximum speed of 225 km/h. It has a range of up to 320km. Designer Alois Ruf points out that in addition to its impressive performance statistics, the eRUF boasts excellent green credentials. It runs at 80 to 90 percent efficiency, compared to the 25 to 30 percent efficiency of a normal petrol engine.
So, it would appear that it is only a matter of time until we can enjoy excellent performance without feeling the guilt of environmental vandalism.
